Fixed fire protection systems are critical safety features designed to protect buildings and occupants in the event of a fire. These systems are specifically designed to detect, control, and extinguish fires without human intervention. They typically consist of fire sprinkler systems and fire suppression systems. Fire protection systems are designed based on the size and complexity of the building and the hazards present within it. The design process involves identifying the areas of the building that require protection, determining the most effective fire protection measures to be employed, and calculating the amount of water and pressure required for each sprinkler head.
